Also have everything to make this bike street legal. A Baja Designs enduro kit with headlight, turn signals, rear fender with tail light and license plate hold built in. Also have a WR stator and flywheel to make all light work. This can be bought a for little extra.

Biggest difference is weight, newer 450's have an aluminum frame rather than the heavy steel frames. Then you look at the power to weight ratio with the extra power from a 450. My buddy had a 426, nice bikes but hard to start. GLWS
